LED驱动电源如何测试 ?

现在大多数工程师在测试LED电源时,有的用LED灯珠,有的用普通型的电子负载,有用1000多元,有用3000元的,但市面上大多的电子负载是不能模拟LED灯珠的,所以,测试出来的功率因数应该是不正确的.这也是为什么CHROMA,以及博计推出专用的LED电子负载. 同时,深圳新能基科技也推出了相应的电子负载,具有LED,CC,CP,CV,CR等五种模式,不但可以测试LED电源,也可以测试充电器,适配器等电源,是一个多功能的电子负载.具有与CHROMA,博计一样的功能,但价格相对应来说要低很多.

预计年底可以量产,敬请大家的期待! (同时,新能基将参加 电源网11月电源技术论坛,届时请大家参观指导!)

但,具有测试LED功能的电源测试系统,新能基科技早电子负载一步推了出来,一经推出得到广大电源企来的青睐.

真正实现LED电源测试的自动化, 为电源企业提高生产效率,降低测试成本.

还是小型化的自动测试系统更好,也代表未来的自动测试发展方向。各项测试指标和控制都可在一个ARM中完成,嵌入式,智能化,网络化。体积小,安装维护方便,价格也低。

另外,如果要测调光,要考虑调光的范围,线性和闪烁,还要考虑如何控制自动调光。
